Another object is to provide im roved mechanism whereb the mechanism is locked and only released y the introduction of a com.

Another object is to provide mechanism which will not be actuated by a iece of metal of less thickness or greater t 'ckness than the desigpated coin.

Another 0 jectis to provide improved coin ejecting mechanism.

Another object is to provide mechanism to lock the indicating pointer against more than one movement for each coin inserted, or before the coin has been registered. I

It further consists in certain details of form, combination. and arr ngement, all of which will be more'fullyse forth in the description of the accompanying drawings in which Figure 1 is a front'elevation of my improved mechanism, showing the case in section on line a) 'u of Fig. 2. Fig. 2 is a sectional view through the casing showing the mechanism in side elevation with parts broken away. Fig ,3 is a perspective view of the coin admitting and mechanism locking member. Fi 4 is a detail view of the coin actuated mec anism charged with two coins.

Fig. 5 is a perspective view of the sliding coin receiver. Fig. 6 is a perspective view of the stationary coin receiver Fig. 7 is a detail top plan of the coin ejector. Figs. 8, 9, and 10 are detail views of the several progressive positions of the coin.

My im roved mechanism is adapted to be emp oye as a coin operated weighing machine, as-a vending machine, or as a combined weighing and vending machine.

In the accompanying drawings A represents the casing.

an ordinary scaleplatform, not shown, to the levers of which spring B isconnected by a rod b and yoke b.

0 represents a pointer pivoted upon a shaft 0 and adapted to indicate upon a scale c the weight on the scale platform. The pointer Qis actuated by a pivoted segment D mesh 'mg' with a pinion c on shaft 0. A size 0 prevents the segment turning too far. he

segment D can only turn when the ratchet toothed segment d is freed by the pawl 11, which is effected b an incline (l -carried by pivoted lever d lifting pawl (1 out of engagement with segment d. The segment D is actuated by means of a sprin (1* attached at one end to an arm of yoke 3 to which the lower end ofspring B is attached, and at the opposite end to an adjustablemember (1 adapted to move along arm d to and from the center on which segment D is ivoted. The adjustment of member 11 ena les the movements of the pointer to be proportioned to the dimensions of the scale in order 'to indicate the correct weight upon the scale. I

The coin- T to actuate the mechanism after first assing throu h achannel where washers, 'sks of less diameter than the coin etc. are separated, reaches the channel E through which it passes to the coin actuating mechanism unless there is alread a coin therein, in

which case the coin is he d in the channel E I by finger f until after the preceding coin has been ejected, The coin actuating mechanism comprises a frame G secured to the easin A and provided with horizontal ways to guide the sliding .plate H. A stationary late'I secured at its corners to studs 9 roecting up from frame G holds the sli ing late H in place. The forward end of plate I orms a'vertical stationary plate or 'aw '41 .against which normal] rests the ribs of a vertically pro'ecting p ate or 'aw it" carried by the mova le late H. T e channel h;

between the jaws 'i is slightly tapered and of just sufiicient width to catch a coin, but ada ted to permit the free passage of a disk of t e same diameter .but a slight fraction thinner than the coin, while a disk of greater thickness would'not the casing A.

The member F is loosely pivoted at f to an ear '5 rojecting from the 'plateI and its rear or 1e t hand portion is heavier than its forward portion causing it to normally stand in the position shown in Fig. 2 with the'finger fprojecting through slot '11 and spanning pass the initial "slot in the channel It with its end resting against jaw h. In this position a stud f engages an offset h of a cam plate It carried by member H to lock member H against forward movement. As soon as a com enters between the jaws 'i h it strikes the finger and tilts member F, disengaging stud from the offset h and causing finger f to project into channel E to prevent the passage of another coin. As the plate H moves forward the cam late h assing beneathstud f locks mem er F in t e posltion indicated in Fig. 4. Members H I have central longitudinal s ots h '1'. to receive the free end In of a crank arm K which is rigidl mounted on a shaft k adapt-' ed to be turne by the operator by means of a crank k on the outside of the casing, said ward it successively assumes the positions Figs. 8, 9, and 10 in the final position forcing the coin downward by means of ear k until at the limit of forward movement of arm K the coin is grasped by the upwardly turned end I of the ejector L, which is pivotally supported by ears 9 from frame G and is held in position to engage the coin by a spring 9 pgosition to receive anothercoin.

As' the crank arm K moves backward the coin and plate H are held by ejector L until the crank arm K strikes the rear end of slot 72, in the plate H when the coin and plate H are thereby released from the ejector and the coin tips over and drops through into a coin receiver, while plate H is returned to The arm is returned to original position by spring The e'ector serves to prevent the coin and plate returning with arm K in such relation as not to drop the coin. A pawl N is adapted to engage a series of ratchet teeth on the crank arm K .to insure the arm K making afull forward movement to bring the coin into en agement with the ejector. As soon as the ast ratchet tooth of crank arm K is passed the crank arm is free to return by tipping pawl N backward until it has been assed by all of said teeth. When the pawl K reaches the depression in rear of proectionls it resets itself ready for the next forward movement of the crank arm. A spring n serves to holdthe pawl N in position to effect said movements. Plate H carries a stud 71. which engages a slot in the lower end of arm (i to retract the pawl 61 A stud h at, the opposite side of plate H may be employed to reciprocate a crank arm M loosely mechanism, not shown,

journaled on shaft k, and to which crank arm is attached a link or. connecting rod m by means of which a coin actuated vending ma be actuated. The mechanism herein ill ustrated and described is capable of considerable modificat1on w1thout departing from the principle of my mventlon.

Having described my invention, what I claim is:

1. In a mechanism of the character indicated,- a coin chute, a stationa receiving jaw, a movable receiving jaw, sai jaws being positioned with an intervemng space to receive a coin, a cam plate movable in unison with said movable jaw, and a pivotally supported member having one finger to enter the space between the receiving jaws, and another finger to enter and close the passage of the coin chute, said member carrying a stud to engage said cam late.

2. In a mechanism of the character indicated, a coin chute a stationary receiving jaw, a movable receiving jaw, said jaws meeting so as to form a coin receiving passage of a width to catch and hold a coin, and to permit the passage of an object of less thickness than a coin, slots through the center of said jaws, and a reciprocating member traveling in said slots and adapted byengaging a coln to move said movable jaw away from said'stationary jaw, and then to release the coin.

. 3. In a mechanism of the character indicated, a coin chute, 'a stationary receiving jaw, a movablereceiving jaw, a channel between said jaws to receive a coin, central slots through said jaws, and a crank arm traveling in said slots and having projections above and below the coin to. engage a coin in said channel and to convey-said coin to a different position and to force the coin downward, and a spring actuated coin ejector adapted to grasp and hold the coin until tripped, and then to eject the coin.

4. In a mechanism of the character indicated, a coin chute, a stationary receiving jaw, a. movable receiving jaw, a channel between said jaws to receive a coin, central slots through said jaws, a crank arm adapted to travel in said slots and provided with a projection above the coin adapted to progressively force thecoin downwardly as said crankarm advances, and means to actuate said crank arm. n

In testimony whereof I have'afiixed my signature in presence of two witnesses.
